## Coordinate System
### Room Coordinates vs Canvas Coordinates
The dungeon editor uses a two-tier coordinate system:
1. **Room Coordinates**: 16x16 tile units (as used in the ROM)
2. **Canvas Coordinates**: Pixel coordinates for rendering
#### Conversion Functions
```cpp
// Convert room coordinates to canvas coordinates
std::pair<int, int> RoomToCanvasCoordinates(int room_x, int room_y) const {
return {room_x * 16, room_y * 16};
}
// Convert canvas coordinates to room coordinates
std::pair<int, int> CanvasToRoomCoordinates(int canvas_x, int canvas_y) const {
return {canvas_x / 16, canvas_y / 16};
}
// Check if coordinates are within canvas bounds
bool IsWithinCanvasBounds(int canvas_x, int canvas_y, int margin = 32) const;
```
### Coordinate System Features
- **Automatic Bounds Checking**: Objects outside visible canvas area are culled
- **Scrolling Support**: Canvas handles scrolling internally with proper coordinate transformation
- **Grid Alignment**: 16x16 pixel grid for precise object placement
- **Margin Support**: Configurable margins for partial object visibility
## Object Rendering System
### Object Types
The system supports three main object subtypes based on ROM structure:
1. **Subtype 1** (0x00-0xFF): Standard room objects (walls, floors, decorations)
2. **Subtype 2** (0x100-0x1FF): Interactive objects (doors, switches, chests)
3. **Subtype 3** (0x200+): Special objects (stairs, warps, bosses)
### Rendering Pipeline
1. **Object Loading**: Objects are loaded from ROM data using `LoadObjects()`
2. **Tile Parsing**: Object tiles are parsed using `ObjectParser`
3. **Graphics Caching**: Frequently used graphics are cached for performance
4. **Palette Application**: SNES palettes are applied to object graphics
5. **Canvas Rendering**: Objects are rendered to canvas with proper coordinate transformation
### Performance Optimizations
- **Graphics Cache**: Reduces redundant graphics sheet loading
- **Memory Pool**: Efficient memory allocation for rendering
- **Batch Rendering**: Multiple objects rendered in single pass
- **Bounds Culling**: Objects outside visible area are skipped
- **Cache Invalidation**: Smart cache management based on palette changes
## User Interface

### Basic Object Editing
```cpp
// Load a room
auto room_result = dungeon_editor_system_->GetRoom(0x0000);
// Add an object
auto status = object_editor_->InsertObject(5, 5, 0x10, 0x12, 0);
// Parameters: x, y, object_type, size, layer
// Render objects
auto result = object_renderer_->RenderObjects(objects, palette);
```
### Coordinate Conversion
```cpp
// Convert room coordinates to canvas coordinates
auto [canvas_x, canvas_y] = RoomToCanvasCoordinates(room_x, room_y);
// Check if coordinates are within bounds
if (IsWithinCanvasBounds(canvas_x, canvas_y)) {
// Render object at this position
}
```
### Object Preview
```cpp

# Yaze Dungeon Editor: Master Guide
**Last Updated**: October 4, 2025
This document provides a comprehensive overview of the Yaze Dungeon Editor, covering its architecture, ROM data structures, UI, and testing procedures. It consolidates information from previous guides and incorporates analysis from the game's disassembly.
## 1. Current Status & Known Issues
A thorough review of the codebase and disassembly reveals two key facts:
1. **The Core Implementation is Mostly Complete.** The most complex and critical parts of the dungeon editor, including the 3-type object encoding/decoding system and the ability to save objects back to the ROM, are **fully implemented**.
2. **The Test Suite is Critically Broken.** While the core logic is in place, the automated tests that verify it are failing en masse due to two critical crashes:
* A `SIGBUS` error in the integration test setup (`MockRom::SetMockData`).
* A `SIGSEGV` error in the rendering-related unit tests.
**Conclusion:** The immediate priority is **not** feature implementation, but **fixing the test suite** so the existing code can be validated.
### Next Steps
1. **Fix Test Crashes (BLOCKER)**:
* **`SIGBUS` in Integration Tests**: Investigate the `std::vector::operator=` in `MockRom::SetMockData` (`test/integration/zelda3/dungeon_editor_system_integration_test.cc`). This may be an alignment issue or a problem with test data size.
* **`SIGSEGV` in Rendering Unit Tests**: Debug the `SetUp()` method of the `DungeonObjectRenderingTests` fixture (`test/unit/zelda3/dungeon_object_rendering_tests.cc`) to find the null pointer during test scenario creation.
2. **Validate and Expand Test Coverage**: Once the suite is stable, write E2E smoke tests and expand coverage to all major user workflows.
## 2. Architecture
The dungeon editor is split into two main layers: the core logic that interacts with ROM data, and the UI layer that presents it to the user.
### Core Components (Backend)
- **`DungeonEditorSystem`**: The central coordinator for all dungeon editing operations, managing rooms, sprites, items, doors, and chests.
- **`Room`**: The main class for a dungeon room, handling the loading and saving of all its constituent parts.
- **`RoomObject`**: Contains the critical logic for encoding and decoding the three main object types.
- **`ObjectParser`**: Parses object data directly from the ROM.
- **`ObjectRenderer`**: A high-performance system for rendering dungeon objects, featuring a graphics cache and memory pool management.
### UI Components (Frontend)
- **`DungeonEditor`**: The main ImGui-based editor window that orchestrates all UI components.
- **`DungeonCanvasViewer`**: The canvas where the room is rendered and interacted with.
- **`DungeonObjectSelector`**: The UI panel for browsing and selecting objects to place in the room.
- **Other Panels**: Specialized panels for managing sprites, items, entrances, doors, chests, and room properties.
## 3. ROM Internals & Data Structures
Understanding how dungeon data is stored in the ROM is critical for the editor's functionality. This information has been cross-referenced with the `usdasm` disassembly (`bank_01.asm` and `rooms.asm`).
### Object Encoding
Dungeon objects are stored in one of three formats, depending on their ID. The encoding logic is implemented in `src/app/zelda3/dungeon/room_object.cc`.
- **Type 1: Standard Objects (ID 0x00-0xFF)**
- **Format**: `xxxxxxss yyyyyyss iiiiiiii`
- **Use**: The most common objects for room geometry (walls, floors).
- **Encoding**:
```cpp
bytes.b1 = (x_ << 2) | ((size >> 2) & 0x03);
bytes.b2 = (y_ << 2) | (size & 0x03);
bytes.b3 = static_cast<uint8_t>(id_);
```
- **Type 2: Large Coordinate Objects (ID 0x100-0x1FF)**
- **Format**: `111111xx xxxxyyyy yyiiiiii`
- **Use**: More complex objects, often interactive or part of larger structures.
- **Encoding**:
```cpp
bytes.b1 = 0xFC | ((x_ & 0x30) >> 4);
bytes.b2 = ((x_ & 0x0F) << 4) | ((y_ & 0x3C) >> 2);
bytes.b3 = ((y_ & 0x03) << 6) | (id_ & 0x3F);
```
- **Type 3: Special Objects (ID 0x200-0x27F)**
- **Format**: `xxxxxxii yyyyyyii 11111iii` (Note: The format in the ROM is more complex, this is a logical representation).
- **Use**: Special-purpose objects for critical gameplay (chests, switches, bosses).
- **Encoding**:
```cpp
bytes.b1 = (x_ << 2) | (id_ & 0x03);
bytes.b2 = (y_ << 2) | ((id_ >> 2) & 0x03);
bytes.b3 = (id_ >> 4) & 0xFF;
```
### Object Types & Examples
- **Type 1 (IDs 0x00-0xFF)**: Basic environmental pieces.
* **Examples**: `Wall`, `Floor`, `Pillar`, `Statue`, `Bar`, `Shelf`, `Waterfall`.
- **Type 2 (IDs 0x100-0x1FF)**: Larger, more complex structures.
* **Examples**: `Lit Torch`, `Bed`, `Spiral Stairs`, `Inter-Room Fat Stairs`, `Dam Flood Gate`, `Portrait of Mario`.
- **Type 3 (IDs 0x200-0x27F)**: Critical gameplay elements.
* **Examples**: `Chest`, `Big Chest`, `Big Key Lock`, `Hammer Peg`, `Bombable Floor`, `Kholdstare Shell`, `Trinexx Shell`, `Agahnim's Altar`.
### Core Data Tables in ROM
- **`bank_01.asm`**: Contains the foundational logic for drawing dungeon objects.
- **`DrawObjects` (0x018000)**: A master set of tables that maps an object's ID to its drawing routine and data pointer. This is separated into tables for Type 1, 2, and 3 objects.
- **`LoadAndBuildRoom` (0x01873A)**: The primary routine that reads a room's header, floor, and object data, then orchestrates the entire drawing process.
- **`rooms.asm`**: Contains the data pointers for all dungeon rooms.
- **`RoomData_ObjectDataPointers` (0x1F8000)**: A critical table of 3-byte pointers to the object data for each of the 296 rooms. This table is the link between a room ID and its list of objects, which is essential for `LoadAndBuildRoom`.
## 4. User Interface and Usage
### Coordinate System
The editor manages two coordinate systems:
1. **Room Coordinates**: 16x16 tile units, as used in the ROM.
2. **Canvas Coordinates**: Pixel coordinates for rendering.
Conversion functions are provided to translate between them, and the canvas handles scrolling and bounds-checking automatically.
### Usage Examples
```cpp
// Load a room
auto room_result = dungeon_editor_system_->GetRoom(0x0000);
// Add an object
auto status = object_editor_->InsertObject(5, 5, 0x10, 0x12, 0);
// Parameters: x, y, object_type, size, layer
// Render objects
auto result = object_renderer_->RenderObjects(objects, palette);
```
## 5. Testing
### How to Run Tests
Because the test suite is currently broken, you must use filters to run the small subset of tests that are known to pass.
**1. Build the Tests**
```bash
# Ensure you are in the project root: /Users/scawful/Code/yaze
cmake --preset macos-dev -B build
cmake --build build --target yaze_test
```
**2. Run Passing Tests**
This command runs the 15 tests that are confirmed to be working:
```bash
./build/bin/yaze_test --gtest_filter="TestDungeonObjects.*:DungeonRoomTest.*"
```
**3. Replicate Crashing Tests**
```bash
# SIGSEGV crash in rendering tests
./build/bin/yaze_test --gtest_filter="DungeonObjectRenderingTests.*"
# SIGBUS crash in integration tests
./build/bin/yaze_test --gtest_filter="DungeonEditorIntegrationTest.*"
```
## 6. Dungeon Object Reference Tables
The following tables were generated by parsing the `DrawObjects` tables in `bank_01.asm`.
